[QUOTE="BackdoorArts, post: 338579, member: 9240"] The answer is, as always, [I]it depends[/I]. The more severe the differences in the lighting situation the more you'll benefit from having the little gaps filled in. A [B][I]lot[/I][/B] depends on the skills of the person doing the post processing as well, in particular because a well exposed '0' image from a D800 has 9 stops of dynamic range already present in the RAW file, giving you all the well-metered pieces of the -4 to +4 stop images. So, the -4 image really gives you -8EV to +1EV light information, while the +4 image gives you -1EV to +8EV light information, expanding your overall light information from [B]-4 to +4[/B] to -[B]8 to +8[/B]. That said, you wouldn't [I]necessarily[/I] need anything other than a 3 image bracket (-4, 0, +4) to give you the same light information. So, why shoot more? The reason you do has less to do with how much light information you have access to, it's has to do with how well the program you're using plays with that light information when it's in 3 files vs. 5, 7 or 9 files. My experience is that giving the program more files to cull from will allow you to create a more natural looking image from the result, with less noise. Given that you can fairly easily produce +/-3EV images using LR or ACR from a RAW file, I was able to turn a 3 exposure HDR series into 5, 7 & 9 exposure HDR series, and I used various combinations with the same set of presets in HDR Efex Pro 2 to see how the treatments would differ ([URL]http://nikonites.com/hdr/21994-playing-3-exposure-hdr-series.html[/URL]). The differences are very subtle, but they are perceptible, mainly in the fine details of darker areas. I've used upwards of 13 images to create a single HDR in a dimly lit chapel environment with bright sunlight beaming through the stained glass windows, and can say for sure that I would never have been able to capture these with 3 or even 5 images...
